Its in the ad details. No computer. At moment its running on Vinyl Cut Pro Demo. You can buy non demo from as little as 55 euro. Spare blades are still available as are all parts for this machine which I can provide a link to . I have manual. About 12 years old

I'm not sure what that is, but I've searched online and found Anchor sand blast tape which comes in different varieties. They sell rolls that are cuttable on all plotters https://www.itape.com/en/products/stencil. The blades on all plotters including mine can be set to different weights to cut thicker materials. You are certainly welcome to try before you buy

@Alan Whitty1: Yes you can see it working tomorrow. The software you run the plotter off determines what it will cut, eps, ai, plt, pdf etc. I have this running with a trial version of vinyl cut pro. As its a trial the program cuts sample files to the plotter(whatever comes with the trial)
If you google that software you will see it will cut any file format including pdf. The plotter just follows orders
